WFRT TECHNOLOGY
We introduce WFRT®, “Wafefront Ray Tracing Technology”, the
exclusive optimization model developed by Pro.Crea.
In the model the lenses and the eyes are placed at their respective position in the real
world. Along with the rx data, all parameters provided by the user are taken into account,
including back vertex distance, pantoscopic angle, frame wrap and working distance.
A bundle of rays is traced from different locations depending on the gaze direction and
the position of the objects in the real world. The resulting wavefront is then evaluated at
the exit pupil, at a finite size, and then optimized for the best vision quality experience
for the user.
